COMBINED WRENCH AND LOOK FOR SHUT-OFF COCKS.

The invention has for its principal object to provide a simple andinexpensive devicev which will be efiicient as a lock to preventunauthorized tampering with valves to open and close the same and whichmay serve as a suitable wrench for operating the valve when not in useas a lock.

The above and other objects and the novel features of the invention willbe apparent from the following description, taken in connection with thedrawing, in which,

Figure 1 is a side elevation of a shut-off cock showing applied theretothe device embodying my invention; Fig. 2 is an end elevation,illustrating the device serving its locking function; Fig. 8 is an endelevation, illustrating the device serving its wrench function; Fig. 1is a perspective view of the device including the key and padlock forlocking the device to the cock.

Referring to the drawing, the valve may be of any ordinary or preferredconstruction, and in the illustration comprises a casing 10 having theusual turning'plug 11 fitting therein the latter being provided with astem 12 which extends outside the casing 10 and is square or angular inshape. The hexagon extensions of the casing 10 are of the usualconstruction and suitably threaded to receive and couple the ends ofpiping such as the pipe 15.

The combined locking device and wrench comprises a part which fits thestem 12 of the plug 11 and parts connected therewith and surrounding thevalve casing or pipe leading thereto and locked together by a A flatplate 16 having a square or angularly shaped hole 17 extendingtherethrough is integrally secured to a U-shaped member comprising theparallel limbs or legs 18 and 19 which are spaced apart a sufficientdistance to straddle the end of the casing 10 or the pipe 15 leadingthereto. The plate 16 and the Specification of Letters Patent.

legs 18, 19 are arranged at right angles to each other the plate beingintegrally joined to the U-shaped member at the bend in the latter. Neartheir ends the legs 18, 19 have rectangular holes 20 and 21 extendingtherethrough to receive the narrow portion 22 of the bolt or keycomprising a bar K which has a T-head 23 larger in dimension than theholes 20, 21 to limit its movement through the hole 21. A hole 24Lextends through the key at the end opposite the head 23 and when inlooking position it extends beyond the opposite leg 18 so that the hole24 will be outside to receive the hasp 25 of a padlock 1?. r

The use of the device will be apparent from the drawing and foregoingdescription. When in use as a means for locking theplug 11 in a closedor open position, as shown in Figs. 1 and 2, the stem 12 is fitted intothe hole 17 with the U-shaped part placed in position so that the legmembers 18 and 19 will be disposed on opposite sides of a part of thevalve or a pipe attached thereto. The part 22 of the key K may then beslipped through the holes 20, 21 and the shackle 25 passed through thehole.24 in the end of the key. Thus the plate 16 is locked in positionso that it cannot turn and the plug is therefore locked in a position sothat it cannot be turned. Under certain condit-ions it is not desirableto use the lock and key, the device being sufficient in itself to lockthe plug against accidental rotation under such conditions.

The fact that the opening 17 extends through the plate 16 and the arms18, 19 are arranged at right angles thereto, makes it possible toreverse the device and use the same as a wrench. hen inuse as a wrench,as indicated in dotted lines in Fig. 1 and in end elevation in Fig. 3,the opening 17 in the plate 16 is fitted over the stem 12 and theU-shaped part of the device placed in position so that the parallelmembers 18, 19 will extend upwardly from the valve. The legs 18, 19provide a convenient grip and lever for turning the part 16 which fitsthe valve stem.

It will be seen that I have provided a simple, inexpensive device whichmay readily be applied to lock the valve and may also be used as awrench.

Various modifications are possible without departing from the spirit ofthe inven- Patented July 21, 1914.

tion and therefore I do not Wish to belirnited to the exact details asshown and described.

Having thus described my invention what I claim and desire to secure byLetters Patent is:

1, The combination with a valve casing having a cutolf plug therein, ofa combined lock and Wrench therefor comprising a plate having an openingtherethrough, parallel members integral With said plate, extending atright angles thereto and spaced apart so as to fit on opposite sides ofa part leading from the valve casing, and means for locking the outerends of said members together, said plate and members integral therewithbeing reversible on the valve stem toserve as a Wrench, the saidparallel members forming the gri of the Wrench. 7 y I V 2. A combinedlocking device and Wrench of the class described, comprising a substanti'ally U-shapedmember and an apertured plate integrally joined to saidmember at the bend in the U and extending laterally there from, saidplate being reversible and the limbs of said member serving as a handlewhen the device is used as a Wrench.

' 3. A device of the class described, comprising a substantiallyU-shaped member having holes at the ends of the limbs there of, a headedfastening bar extending be- J tween said limbs and having a shankadapted to pass through the holes'at the ends of 1 I said limbs, meansengaging the end of the iiopies of this 'patentma y be obtained for livecents shank of said bar and cooperatin with one of said limbs to lockthe bar in place, and a plate integral With said member at the bendtherein and extending laterally therefrom and having a part adapted tofit a portion i of a valve.

4. .A' combined locking device and Wrench for a valve, comprising asubstantially U- shaped member having holes extending vthrough the endsof the limbs thereof, a

T-headed fastening bar having a shank adapted to'extend through theholes in said limbs to connect the latter, the head of said bar engagingthe outer side of one limb to limit its movement in one direction, andsaid shank having a hole in the end thereofpro-- jecti'ngbeyond theouter side of the other limb,

In testimony whereof I afiix signav ture in presence oftWo Witnesses.
